SEPARARLE .RIM FOR VEHICLE-WHEELS.

To all whom it may Wham-- Be it known that I, Ton J. Mann, a citizen ofthe United States, residing at Youngstown, in the county-of 'Mahoning'and State of Ohio, have invented certain new and useful Improvements inSeparable Rims for Vehicle-Wheels; and I do hereby declare the followingto be a fuil', clear, and exact description of the invention, suchaswill enable others skilled in the art to which it appertains to make anduse the same.

showin My invention relates'to vehicle wheels and comprises, moreparticularly stated, a sectional rim for receiving and detachablyretaining pneumatic or other 'tiressuch' as employed in .automobileconstruction.

The chief'object of my invention is therefore to provide means forfirmly and securely'holding. .to wheel-rims in operative position, thattype of tires known to the trade'as clencher tires]? in a manner, whichat the same time renders them readily detachable; and my inventionconsists inthe novel form, arrangement, and combination of partshereinafter described,-'particularly.

pointed out and claimed.

In the drawings which form part of this application and whereoncorresponding reference characters indicate like" partsm the severalviews Figure l represents in slde elevation my improved wheel-rlm on avery much-reduced scale. Fig. 2- is a transverse, sectional view of therim assembled, show-- ing its relation .to the telly andone spoke of thewheel, Fig. 3 is a fragmentary view in side elevation that ortion of therim inc uding the looking or ey-block and its retaining screw, F ig. ais a sectional view similar to Fig. 2, but taken through the lockingblock and screw aforesaid. Fig. 5 is a horizontal section through theremovable arts on the line surrounded by the fixed rim member or section3, which latter is by preference endless or continuous and shrunk u ponits felly 2 or otherwise secured thereto in any approved manner.

One side of the'fixed member or section 3 is formed with a continuouscurved-over Specification of Letters iatent. v Patented 1 3 '7', 1910,Application filed December 19, 1905 Serial No. 292,451.

edge ,tdesigned and adapted to engage the attaching rib or non-elasticbead (not shown) of the well known form of clenchertires. The oppositeside of said section 3 is finished by an'inturned angular and annularflange 5 as shown by Figs. 2 and 4, the function whereof will laterappear. Adjacent to this flange 5 is located the detachable rim section6 also fitted with a continuous curved-over edge 7 corresponding withthat numbered 4, and coacting therewith to clench and retain a tire inoperative position by similarly engaging its opposite attaching rib ornon-elastic bead. The base 8 ofthe rim section 6 finds a support in aslightly depressed seat 9 upon the eriphery of fixed section-3, and isprovide with an inturned-ridge or flange 10 corresponding with thatnumbered 5 against which it snugly fits.

Embracing the flanges 5 and 10 is an open resilient ring 11 havingconverging ends 1212, and channeled upon its exterior surface as at 13.Between the angular ends of ring 11 is located a looking or key block 14the ends whereof correspond with those of said ring, this block beingdrawn into and retained in position by means of a bolt or machine screw15 passing therethrough and threaded into or between flanges 510 of therim sections as indicated by the drawings and particularly by Figs. 4:,5 and 6 thereof.

This being a generaldescription of .my

inventionin its preferred form of construction, it will be here notedthat same may be variously changed and modified to meet specialrequirements of tires and wheels withoutin the least departing from thespirit of my invention as hereinafter claimed. For example, ring 11 maybe either an expansion or a compression ring,

or its sectional contour may be variously altered'so long as itsfunction as a locking ring is. not destroyed. Likewise the retainingscrew 15 may be threaded into a hole formed partly in both flanges 5 and10 as shown by Fig. 5; or, as illustrated by modified Fig. 6, it may bethreaded into a lug formed upon one of said flanges'and recessed intothe other of said flanges; or in some instances the screw or'bolt 15 maybe embedded in the flange or flanges and provided with a nut forthepurpose of seating and retaining the locl ring or key-block 14.

and 10 upon the fixed and The operation of assembling the several partsof my invention when constructed and arranged as illustrated may bebriefly stated as follows: The bead or non-elastic base at one side ofthe outer case or sheathing of a tire is first engaged by thecurved-overedge 4 throughout its circumference. The correspondingcurved-over edge 7 upon the detachable rim section 6 is next broughtinto similar engagement with the opposite bead or base of said tire,whereu on flanges -5 etachable rim sections, respectively, are in closecontact as shown by Fig. 2. At this juncture the resilient locking ring11 is circumferentially compressed or sprung together until its ends12-12 abut, whereupon, owing to its decreased diameter,- same mayreadily be passed within the confines of flanges '5 -10. This ring isthen permitted to expand, or is positively expanded, until it snuglyembraces within its channel 13 the aforesaid fianges, and is therepositively keyed in locked position by agency of the block 14 introducedbetween its ends I212. Retaining screw 1.5 is now employed to completethe operation This single screw passing radially through said block 14,engages in screw threaded relation the flanges 5-10, thereby serving toeffectively draw said block to its seat as shown by Figs. 3, 4, andsecurely interlock flanges 5-10 of the fixed and detachable rim sections3, 6, respectively, against accidental dislodgment.

I-Iavingthus described my invention, what I claim and desire to secureby Letters Patent is:

terlocking with said flanges, a block for keying said ring in a lockingposition, and means for'securmgsaid block, substantially as described.

3. In a vehicle wheel, the combination with separable rim sections eachhaving a circumferential locking flange, of an open resilient ringadapted to interlock with said flanges, a key block adapted to expandsaid ring into its locked position, and a retaining screw for" securingtogether the aforesaid bloclnflanges, and ring, substantially asdescribed.

In testimony whereof I aflix my signature, in presence of twosubscribing wit nesses.
